Description
【考案の詳細な説明】 〔産業上の利用分野〕 本考案は、船舶に装備されたプロペラの洗浄装置に関す
る。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a cleaning device for a propeller mounted on a ship.
従来、船舶に装備されたプロペラの洗浄装置は、見当た
らない。Conventionally, no propeller cleaning device equipped on a ship has been found.
従来は、船舶をドックに入れて、足場を架設した後、同
足場から動力式研摩工具にて船尾のプロペラ表面を磨く
ことが行なわれていた。Conventionally, after putting a ship in a dock and constructing a scaffolding, the propeller surface of the stern was polished from the scaffolding with a power type polishing tool.
ところで、上述のように、船尾に装備されたプロペラの
表面を、ドック内の足場から動力式研摩工具にて磨くこ
とにより、フジツボ等の海洋付着物をプロペラ表面から
除去する従来の手段で、多くの手間と時間とを必要と
し、コスト高を招くことになる。By the way, as described above, by polishing the surface of the propeller mounted on the stern with a power-type polishing tool from the scaffolding inside the dock, many conventional means for removing marine deposits such as barnacles from the propeller surface are used. It requires time and effort, which results in high cost.
そこで、小型船では、防汚塗料をプロペラに塗布して生
物の付着を防止することも行なわれているが、信頼性に
乏しく、寿命も１〜２年程度であって、結局ドックで上
記動力式研摩工具を用いる手段に頼ることになる。Therefore, in small boats, antifouling paint is applied to the propeller to prevent the adhesion of living things, but it is unreliable and has a life of about 1 to 2 years. You will rely on the means of using a polishing tool.
本考案は、このような問題点の解決をはかろうとするも
ので、船舶に装備されたプロペラを、ドックや動力式研
摩工具を利用しないでも簡単に洗浄できるようにした、
舶用プロペラ洗浄装置を提供することを目的とする。The present invention is intended to solve such a problem, and makes it possible to easily wash a propeller mounted on a ship without using a dock or a power-type polishing tool.
An object is to provide a marine propeller cleaning device.
上述の目的を達成するため、本考案の舶用プロペラ洗浄

ノズルをそなえ、同ノズルに船内の高圧水源が接続され
たことを特徴としている。In order to achieve the above-mentioned object, the marine propeller cleaning device of the present invention is designed to clean the propeller installed on a ship by directing the jet ports above the propeller to the left and right propeller blades of the propeller. It features a pair of left and right mounted nozzles, and the high-pressure water source inside the ship is connected to the nozzles.

れる。その際、ひねりを付された各プロペラ翼の両翼面
のうち、一方の翼面が左舷側のノズルで洗浄されると、
他方の翼面は右舷側のノズルで洗浄されるようになる。In the above-described marine propeller cleaning device of the present invention, when the ship is in a ballast state, trim of the hull is adjusted to expose the upper part of the stern propeller to the surface of the water, and the turning gear rotates the propeller to rotate the propeller above the propeller. The propeller blades are washed with high-pressure water ejected from the left and right nozzles. At that time, if one of the two blade surfaces of each propeller blade with a twist is washed by the port side nozzle,
The other blade surface will be cleaned by the starboard side nozzle.
本装置の使用にあたっては船体の入渠を必要としないの
で、小まめにプロペラの洗浄作業を行なうことが可能と
なり、プロペラに生物が付着しかかった状態や生物の付
着直後の比較的除去の容易な状態で洗浄作業が行なわれ
るようになる。The use of this device does not require the dock of the hull, so it is possible to perform small-scale cleaning of the propeller, and it is relatively easy to remove the propeller when organisms are attached to it or immediately after the attachment of organisms. Cleaning work will be performed in this state.
また、船舶の停泊中における余剰エネルギーを利用して
高圧水を作成し、ノズルを通じてプロペラ表面に高圧水
を噴き付けることも行なわれる。In addition, it is also possible to create high-pressure water using surplus energy while the ship is at anchor and spray the high-pressure water onto the propeller surface through a nozzle.
以下、図面により本考案の一実施例としての舶用プロペ
ラ洗浄装置について説明すると、第１図はその側面図、
第２図はその正面図である。Hereinafter, a marine propeller cleaning apparatus as an embodiment of the present invention will be described with reference to the drawings.
FIG. 2 is a front view thereof.
第1,2図に示すように、船体Ａの船尾に装備されたプロ
ペラ８の上方において、同プロペラ８を洗浄するための
左右一対のノズル1,1が、同プロペラ８の左右のプロペ

着されている。As shown in FIGS. 1 and 2, above the propeller 8 mounted on the stern of the hull A, a pair of left and right nozzles 1, 1 for cleaning the propeller 8 are provided on the left and right propeller blades of the propeller 8. Each of them is attached to the hull 1A so that the jet ports 1a are directed.
そして、各ノズル１には、給水管２を介して船内の高圧
水源が接続されている。A high-pressure water source in the ship is connected to each nozzle 1 via a water supply pipe 2.
すなわち、給水管２は船内のエジェクタ３の吐出口へ連
結されており、バルブ６を開いて取出される雑用水が、
送水管４を通じエジェクタ３へ導かれるとともに、同エ
ジェクタ３には高圧エアタンク７からバルブ５を通じ作
動流体としての高圧空気が導かれるようになっていて、
これにより高圧水がノズル１の噴出口1aからプロペラ８
へ向け噴出しうるようになっている。That is, the water supply pipe 2 is connected to the discharge port of the ejector 3 in the ship, and the miscellaneous water extracted by opening the valve 6 is
While being guided to the ejector 3 through the water supply pipe 4, high-pressure air as a working fluid is guided to the ejector 3 from the high-pressure air tank 7 through the valve 5.
As a result, high-pressure water flows from the jet port 1a of the nozzle 1 to the propeller 8
It is possible to squirt toward.
上述の構成により、プロペラ８の洗浄に際しては、バラ

面のうち、一方の翼面が左舷側のノズル１で洗浄される
と、他方の翼面は右舷側のノズル１で洗浄されるように
なる。With the above-described configuration, when the propeller 8 is washed, trimming of the hull A in the ballast state is performed to expose the upper portion of the propeller 8 to the sea surface, and then the propeller 8 is rotated by a turning gear (not shown), High-pressure water from the nozzle 1 is sequentially sprayed onto each propeller blade. At that time, when one of the blade surfaces of each of the twisted propeller blades is washed by the port 1 nozzle 1, the other blade surface is washed by the starboard nozzle 1 .
このようにして、プロペラ８の各プロペラ翼の両翼面に
付着した海洋生物などが、高圧水により十分に除去され
るが、このようなプロペラ８の洗浄作業は、船体Ａの入
渠を必要としないので、小まめに実施される。In this way, the marine organisms and the like adhering to both blade surfaces of each propeller blade of the propeller 8 are sufficiently removed by the high-pressure water, but such a cleaning operation of the propeller 8 does not require the dock of the hull A. So it will be done diligently.
したがって、海洋生物がプロペラ８に強固に付着する前

の増加を防止することができる。Therefore, the marine organisms can be removed before they firmly adhere to the propeller 8, and the propeller 8 can be kept in a clean state at all times, so that the propeller efficiency is maintained as planned and, in turn, the ship. It is possible to prevent an increase in the operating cost of the.
なお、ノズル１へ高圧水を供給するための高圧水源とし
